Single Phase STS Keypad Prepaid Meter with IEC62056-21 Protocol
General introduction
1) Keypad Prepaid Meter has the functions such as metering, monitoring, alarm, display, communication and load control, etc.
2) It adopts STS standard encryption algorithm to exchange the
information based on TOKEN, Advantages of the meter are high metering accuracy, high level
security, strong compatibility, easy operation, etc.
Main functions
- Support UIU
- UIU communication interface: PLC, RF or twist-wire are optional.
- Step tariffs
- TOU: Four tariffs; two sets of time zone tables; two sets of time period
tables; support public holidays and weekends.
- Friendly power supply:Support emergency credit.
- Communication interface: Optical port and RS485 interface are
available;PLC,RF,GPRS and twist-wire interface are optional.
- Events logs:Detecting and recording events such as current reverse, magnetic
influence, phase bypass, meter cover open, terminal cover open,
overvoltage, under voltage, etc.
- Anti-tamper: Detecting current reverse, magnetic influence, phase bypass, meter
cover open, terminal cover open etc., at the same time, the meter
can disconnect power supply which is configurable when the tampers
occur.
- Audio and visual alarm: Audio and visual alarm which can be configurable can be for power
flow reverse, magnetic influence, phase bypass, meter cover open,
terminal cover open, etc.
- Load control: Detecting the customer's load status, it can alarm or disconnect
the load when overload.
